Quality of concrete explains considerably the state of affairs involved in the production of concrete in a particular area. The antecedents of the production process to a greater extent therefore have a way of predicting the expected quality of a product. Hence, the degree of relationship between the quality of concrete and its production characteristics is determined in the study. Field work adopted in the study comprises activity sampling and ex post facto experimental designs. These two different research designs were applied to obtain data for performance assessment of activities involved in the production procedures and laboratory tests of concrete produced at various sites in the study area respectively. The corresponding data obtained in the field work are in ordinance and ratio scales of measurement. Regression analysis was used to establish a casual relationship between the two variables - performance level of the production characteristics (x) and the compressive strength (y) of the concrete at various sites in the study area. A model relationship of simple regression analysis for the dependent and independent variables is established. Finding reveals that the better the ranking of sites in compliance with the standard practice of production characteristics, the higher the compressive strength property of the concrete produced on site; hence the linear relationship. The coefficient of determination shows that 93% of changes in the strength property of concrete are caused by the production characteristics. Although the highest value of compressive strength obtained as 10.80 N/mm2 goes with the best state of affairs of the production characteristics in the study, it does not meet the minimum stipulated specification for the strength. Hence, other critical factors such as; aggregate type, and mix design should be considered for desired quality of concrete in the study area. Besides, enforcement of uniformity in production process as standard practice by all the firms should as a matter of urgency be implemented formally by the government in the state for improved quality of concrete in general.
